IMPROVEMENT lN PRQCESSES OF FORMING YARN BY FELTING.

Specification forming part of Letters Patent- No. 9,653, dated April 5,1853.

To all whom it may concern:

Be it known that I, JOHN. H. BLOODGOOD, of

New Jersey, have invented a new and useful Improvement in theManufacture of Vi oolen Rovings or Untwisted Thread; and I do herebydeclare that the following is a full, clear, and exact description ofthe same.

The nature of my invention consists in the production of a strong feltedroving or untwisted thread of wool capable of being employed for warp orweft in making woven cloth, or for knitting, sewing, and other purposes.

All threads made of wool for the purposes of knitting or sewing are madeby twisting after the wool is carded and condensed into rovings: Thetwisting or spinning processes are expensive, owing to the machinery,time, and labor employed in the said processes.

No roving or uutwisted woolen thread as now made by the commonprocesses, or that has been made heretofore, can be employed for eitherweaving or knitting purposes, because the fibers of the wool are loose,do not adhere together, and draw apart when the least tension force isapplied to them. 7 This difficulty is obviated by felting the rovings asthey come from the carding-machine. This is done by allowing the rovingsto pass through a steam-box, where they are submitted to the action ofsteam and a rolling rubbingmotionof a plate, by which the said rovingsare felted, and thereby made into strong, beautiful, and durableuutwisted thread, and in that state capable of being employed forweaving, knitting, &c., and all the purposes for which twisted threadsor yarns are now employed.

The felted roving or felted uutwisted thread is capable of producing asoft, strong, and beautiful fabric of cloth, and it covers up cottonwarping, which is now so abundantly employed in our manufactures, in amuch superior manner to woolen twisted weft. Cloth made of my feltedroving thread is more easily napped by the teasel than cloth made oftwisted thread, and it is capable of taking a far finer finish in thedressing process. In weaving, the felted roving weft is capable of beingdriven up so close with the lay or driver that it covers up a cotton orlinen warp so completely that the cotton cannot be detected, and itnever can wear out in the same manner as the cotton warps of satiuetsdo, which are made with a weft of twisted woolen thread, (yarn) Theproducing of a strong felted roving or uutwisted felted thread capableof being employed for weft, or thread for knitting, 810., saves all thetroublesome and expensive processes of spinning and doubling andtwisting.

I do not claim any new improvementin inachinery in this specification,as the new manufucture of felted rovings or uutwisted felted thread is anew invention a-ndimprovementin itself, and itean be applied todifferent branches of manufacturing textile fabrics, &c.

- iVhat I claim as myinvention, and for which I desire to secure apatent, is-

The formation of thread or yarn from woolen rovings by the process offelting instead of twisting or spinning, substantially as herein setforth.
